Wirelizard - for a less costly option check out flea markets, carboot sales and charity shops. There was a Waddingtons game based on Jurassic park which contains plastic but very well sculpted dinos. Each box had one T Rex and about a dozen raptors along with a similiar number of little critters whose name eludes me. I've got two boxes over the years and only paid £1.50 - £2.
Nah, I decided that pewter was better than food. Pewter lasts, food just gets eaten!
Another batch of raptors, a pterodon, and some other toys inbound. (actually, I checked the bank accounts and discovered I wasn't quite as broke as I thoght I was, so could afford a small indulgence of pewter.)
But cool to know about the Jurassic Park game, I'll keep an eye out for it in local 2nd hand shops! I also keep meaning to take a 28mm figure into a toy shop or craft store and find some reasonably-sized plastic kid's toy dinos for repainting.
